If you need OrderedDict or OrderedSet, use OrderedCollections.jl, which contains those.
Agreed. These days
DataStructures simply reexports
OrderedCollections so functionally there’s no difference.
If you are using more functionality from
DataStructures you may as well get everything from that package.
However, if you use only
OrderedSet, getting them from
OrderedCollections has the advantage that it’s a smaller and more stable dependency, which helps a lot with keeping up to date with dependency compatibility.
